Replacing RAM in eMachines

[bignad98]

I'm trying to upgrade my sister's old system.  She has an old eMachines with PC2100 RAM and a 400MHz FSB (according to online documentation.)  There is some PC3200 memory on sale.  Will the 3200 work?

Will a memory chip with a faster FSB rating, lower CL rating, and higher PCXXXX number work in an older, slower motherboard?  What does the PCXXXX number mean?

Existing:
eMachines T2542
256MB of PC2100, CL 2.5, 266MHz FSB
Intel 845G chipset
2.50 GHz Celeron processor

Hi, a quick check on crucial showed that you could go up to 2gb.
